I recently had my 1994 Force 120hp rebuilt. I am through the 10 hour break in period and want to change my spark plugs. My mechanic put in NGK-BUHW's but after doing some research to ensure proper installation on the NGK website they recommended the BUHZW. Are the BUHW's going to be alright to continue using (didn't have any noticeable problems) or is there a major difference in the BUHZW that necessitates me returning the BUHW's and getting the BUHZW's?
Also, any tips on how much to torque the plugs after they are hand tight?
Thanks for the help.
